SPECIFICATION 'forming part of Letters Patent N o. 623,776, dated April 25, 1899.

Application filed April 9, 1897. Serial No. 631,404. (No model.)

To CLM zul/tom Lt may concern.-

Be it vknown that I, ALBERT FISCHER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Engines, of which the following is a full, clear,'and exact description, reference being had to the accompanying drawing, forming part o f this specification, in which the figure is a partial longitudinal section of a steam-engine provided with my improved separating-partition.

My invention relates to steam-engines and is designed to prevent the water leaking out of the cylinder from entering` the trunk portion of the engine and there .mixing with the oil used to lubricate the engine, as well as t0 prevent oil I rom coming into contact with the cylinder.

In the drawing, 2 represents a portion of the trunk or inclosing casting of a steam-engine having a cylinder 3. The trunk is provided with cross-headguides 4, in' which moves the cross-head 5, 6 being the connecting-rod. At a point between the cross-head guides and the cylinder I provide a transverse partition 7, having a hole into which is screwed the plate or gland S, having the packing-ring 9 in contact with the piston-rod 10, which passes througlrthis gland. The opposite end 1l of the trunk is depressed to form the ordinary oil-reservoir and contains the crank-shaft bearings. l2 is a pipe by which the oil in the crank-pit maybe drawn oi when desired. It is evident that when this separating-partition is employed the oil within the frame or trunk of the engine will lbe prevented from being thrown back or carried against the cylinder, so that the oil is kept pure, while the Water leaking from the cylinder will be kept out of the oil.

Many changes may be niade in the forni and arrangement of the partition without departing from my invention, and it may be applied to many different types of engines.

I claiml. An engine having a piston-rod, crosshead, crank-shaft and connecting parts, an inclosing frame or casing arranged to contain oil, and a partition-plate between the crosshead guide and the cylinder, having a hole for the pistonerod and bearing around the rod to prevent mixing of the oil and water; substantially as described.

2. An engine having a piston-rod, crosshead, crank-shaft and connecting parts, an inclosing frame or casing arranged to contain oil, and a partition-plate between the crosshead guide and the cylinder, said plate havn ing a hole for the piston-rod provided with a closure-bearing around the piston-rod; substantially as described.

In an engine, a trunk or frame inclosing and having bearings for the cross-head, said trunk having a separating-partition between the cross-head bearings and Athe cylinder and provided with a gland for the piston-rod whereby leakage from the cylinder is kept out of l the trunk.

4. In an engine, a trunk having integral sides and bottom, one end of the trunk having bearings for the crank-shaft, and a depression forming an oil-reservoir, and the other end of the trunk having a cross-head guide, and a partition-plate between the guide and the cylinder and having a gland for the piston-rod.

5. In an engine, a trunk or frame having bearings for the cross-head, said trunk having between the cross-head bearings and the cylinder a separatin g-partition provided with a packing surrounding the piston-rod which passes therethrough.

In testimony whereof I have hereunto set my hand.

' ALBERT FISCHER.
